Chus are enemies from The Legend of Zelda: Twilight Princess. These translucent, amorphous, featureless blobs are found commonly throughout Hyrule, especially in dark areas. Chus can merge with one another to progressively increase in size; when a merged Chu is struck, it will divide into two smaller Chus rather than perish.
Choose a wider carpet stair runner if you want to protect the majority of the wood surface and provide enough surface area for two people to walk up and down the stairs simultaneously. This Old House recommends a standard stair runner design of 32 inches. This width is available at most hardware stores, home improvement centers and carpet stores. Since most stairs have a 36- to 42-inch width, a 32-inch stair runner still provides 2 to 5 inches of visible wood floor space on either side of the runner.
Because of this we measure homes in linear feet or in other words how long of a carpet roll to buy. Since some carpet rolls are 15 feet wide the amount of carpet needed to carpet your home can vary with the size of the carpet roll used. Since most consumers are familiar with square footage measurements the carpet industry uses the standard of square yards instead of linear feet.
